Assuming you taking this for weight loss, it probably works but not by much and it is by no mean, a long-term fix

Not to mention a few side effect to go with it:
Dizziness
Dry mouth
Headache
Upset stomach or diarrhea
Just a few things to consider before you commit into buying and trying them..Personally I'd buy Yohimbine HCL, take that along with a caffeine pill 2o-3o mins before your workout which is HIIT-fasted-Cardio (Sprint 8) - 30 sprint//1 min 30s rest for 8 intervals on a recumbent bike/stationary bike if your/wifey goal is to lose fat. It worked great for me.
